No full textThis board-book version of LM turns out to be quite creative. Ratoncete comes from school every afternoon and goes through the forest looking for adventures. He apparently blasts a horn into the ear of the sleeping lion. Don Leon wants to spank him as a result, but Ratoncete offers an apology, not an offer of help. Later, he happens upon the lion in his trap of ropes. 8 pages, counting both covers. 6½" x 9".Language note: SpanishNo Autho

Markets Equilibrium: The Is-Lm Model
No full text. The purpose of this study is to analyze how the concept of markets equilibrium: the IS-LM Model. This research uses library research method by using reference sources from books and journals according to the theme. The author uses a qualitative method which is explained graphically, namely the market balance of the IS-LM model where the focus is on money and goods markets associated with macroeconomics where researchers take the side of investors. The results of this study are that the balance in the economy is the point where the IS and LM curves intersect. This point provides an interest rate (r) and income level (Y) that satisfies the equilibrium conditions that occur in the goods market and money market. In other words, planned spending equals actual spending, and the demand for real money balances equals the supply. So that the IS-LM balance, it is stated that IS=LM

HOST GUEST COMPLEXATION .48. OCTOL BUILDING-BLOCKS FOR CAVITANDS AND CARCERANDS
No full textThe scope of limitations of the syntheses of octols 1 by the fourfold condensations of various aldehydes withresorcinol and 2-substituted resorcinols are reported. At most, two stereoisomers of 1 were detected, one withC4v and the other with C2u symmetry ( NMR). With aliphatic aldehydes, only 1 (C4u) product was isolatedin yields ranging from 45 to 92%. With 4-substituted benzaldehydes (R = (4-XC6H4)), the yields and isomerratios varied with the character of the X substituent. With X = CH3 and CH3CH2, the C4ajC2v ratios were >32and the yields were 73-96%. With X = H or Br, 0^/0%, values ranged from 1.0 to >30 as a function of reactiontime. With X = OCH3 or X = C6H6, the C4l)/C2„ ratio was 1.5 and the yields were 93 and 99%, respectively.When X = NC, (CHa)3C, H02C, and AcNH, the C4u/C2i. ratios (yields) were <0.03 (52%), 0.03 (28%), 0.4 (79%),and 0.5 (52%), respectively. With X = 02N, OHC, or CH3(CH2)3C=C, no cyclic tetramer was detected. Con-densation of 2-methylresorcinol with CH3CHO gave 79% of the C4a isomer, but with C6H5CHO, C4u/C2u = <0.03(78%). No cyclic tetramer was obtained with either aldehyde and 2-nitroresorcinol or 2-bromoresorcinol. Anindeterminate mixture of isomers was produced with CH3CHO and 2-carboxyresorcinol. Crystal structures oftwo octols 1 (C4„) were determined (A = H, R = CH3 and A = H, R =CH3(CH2)3) as solvates, and these octolsexhibited bowl-shaped conformations. These compounds serve as important starting materials for the synthesesof cavitands and carcerands
Possibilities and testing of CPRNG in block cipher mode of operation PM-DC-LM
No full textThis paper discusses the chaotic pseudo-random number generator (CPRNG), which is used in block cipher mode of operation called PM-DC-LM. PM-DC-LM is one of possible subversions of general PM mode. In this paper is not discussed the design of PM-DC-LM, but only CPRNG as a part of it because designing is written in other papers. Possibilities, how to change or to improve CPRNG are mentioned. The final part is devoted for a little testing of CPRNG and some testing data are shown. © 2016 Author(s)
The safety and effectiveness of different methods of ear wax removal: a systematic review and economic evaluation
No full textEar wax (cerumen) is a natural secretion produced to protect the inner ear from dirt and other fragments by moving these particles towards the outer ear. If this process does not happen properly, wax may build up causing blockage in the ear canal and the possibility of impaction. People with a build up of ear wax may suffer from hearing loss, discomfort and, on occasions, infection. It may present problems in assessing hearing, blocking the view of the ear drum during medical examination and interfering with the fitting or function of hearing aids. Although it is thought to affect between 2% and 6% of the population in the England and Wales, some groups may be at a higher risk, such as those using hearing aids or with small ear canals and/or skin conditions. Recurrence is thought to be high among some of these groups. The consequences of the build up of ear wax in the ear canal are thought to be a common reason for consultation and cost in general practice with over 2 million consultations per year in the NHS.Methods of removal of ear wax include drops, flushing with water in general practice, and removal with suction or probes in specialist clinics. The relative safety and benefits of these different methods of removal remains uncertain. This research will systematically review published and unpublished evidence on the clinical and cost effectiveness of different methods for the removal of ear wax. Where appropriate, it will develop an economic model using data from this systematic review and other relevant sources to estimate the relative costs and benefits of different methods. In addition, the project will provide recommendations for future research to try to help answer any remaining areas of uncertainty
CF/LM-PAEK: Characterisation and sensitivity to critical process parameters for automated fibre placement
No full textThis paper presents an investigation into Automated Fibre Placement process parameters for a novel carbon-fibre-reinforced thermoplastic material based on a low-melt polyaryl ether ketone polymer matrix (CF/LM-PAEK). The primary focus of this investigation is in-situ consolidation, with parameter sets for sample manufacturing selected based on a Design of Experiment method and analysed by means of mechanical and thermal testing. For in-situ consolidation, a maximum shear strength of 33.6 MPa and a crystallinity of 27.3% is achieved. Subsequent tempering increases shear strength up to 46.5 MPa and crystallinity up to 32%. The material was found to be insensitive to layup speed within the tested parameter range (1–15 m/min), achieving similar results for high layup speeds

Fahrul Kurniawan, Perancangan Adaptor Dengan Output 5V DC Menggunakan IC LM 7805, Komprehensif, Jakarta, Pendidikan Teknik Elektronika, Fakultas Teknik, Universitas Negeri Jakarta
Tenaga listrik merupakan tenaga yang dimanfaatkan manusia dalam kehidupannya sehari-hari. Tenaga listrik dimanfaatkan untuk menghidupkan atau menjalankan alat-alat elektronika yang mempermudah aktivitas manusia. Agar dapat menggunakan tenaga listrik pada alat-alat elektronik diperlukan pengubah daya dari arus listrik arus kuat ke arus listrik arus lemah. Konsep pengubahan arus kuat menjadi arus lemah diterapkan dalam bentuk adaptor. Dalam pembelajarannya adaptor memanfaatkan konsep dioda sebagai penyearah arus listrik. Pada program studi Pendidikan Teknik Elektronika, khususnya di Universitas Negeri Jakarta, penerapan konsep dioda sebagai penyearah dituangkan dalam pembuatan adaptor DC oleh mahasiswa. Menggunakan IC LM 7805, penulis membuat adaptor DC dengan keluaran 5V sebagai penerapan konsep dioda sebagai penyarah. Hasil dari perancangan adaptor menunjukkan hasil pengukuran output adaptor bernilai 5V. Hal ini berbanding lurus dengan sifat IC LM 7805 yang meregulasi tegangan output yang masuk ke IC menjadi 5V.

ABSTRACT
Fahrul Kurniawan, Adapter Design with 5V DC Output Using IC LM 7805, Comprehensive, Jakarta, Electrical Engineering Technical Education, Technic Faculty, University State of Jakarta
Electrical power is energy that humans use in their daily lives. Electrical power is used to turn on or run electronic devices that make human activities easier. In order to use electrical power in electronic devices, it is necessary to convert the power from strong current to weak current. The concept of converting strong current to weak current is implemented in the form of an adapter. In the lesson, the adapter utilizes the concept of a diode as an electric current rectifier. In the Electronics Engineering Education study program, especially at Jakarta State University, the application of the concept of diodes as rectifiers is outlined in the manufacture of DC adapters by students. Using IC LM 7805, the author made a DC adapter with 5V output as an application of the diode concept as a rectifier. The results of the adapter design show that the adapter output measurement results are 5V. This is directly proportional to the nature of the LM 7805 IC which regulates the output voltage entering the IC to 5V.

Generalized LM tests for functional form and heteroscedasticity
No full textWe present a generalized LM test of heteroscedasticity allowing the presence of data transformation and a generalized LM test of functional form allowing the presence of heteroscedasticity. Both generalizations are meaningful as non-normality and heteroscedasticity are common in economic data. A joint test of functional form and heteroscedasticity is also given. These tests are further "studentized" to account for possible excess skewness and kurtosis of the errors in the model. All tests are easy to implement. They are based on the expected information and are shown to possess excellent finite sample properties. Several related tests are also discussed and their finite sample performances assessed. We found that our newly proposed tests significantly outperform the others, in particular in the cases where the errors are non-normal. Copyright � 2008 The Author(s).
